ITEM 1.  DESCRIPTION OF BUSINESS

GENERAL DEVELOPMENT OF BUSINESS

Diagnon Corporation (the "Company") was founded in 1981 to develop, produce and
sell diagnostic test kits incorporating monoclonal antibodies to diagnose
certain anemias, infections, and parasitic diseases.  In fiscal year 1988, the
Company discontinued the diagnostic test kit segment of its business to
concentrate on and to expand its contract research base with the National
Institutes of Health (NIH).

Beginning with fiscal year 1988, the Company has been profitable each year.
Company management, recognizing the limited number of new NIH contract
opportunities, has concentrated on maintaining its core base of long-term
contracts, competing on new opportunities when available, and concurrently
pursuing other related business elements.

In the first quarter of fiscal year 1995, the Company entered into agreements
with The Johns Hopkins University to pursue development, testing and possible
commercialization of certain cancer treatment and drug delivery approaches that
had been developed by members of the faculty of The Johns Hopkins' University
(JHU).  The transaction was contingent on the obtaining of financing through a
private placement on a best efforts, non-underwritten basis by Slusser
Associates, Inc., a New York investment banking firm.  The project was to be
implemented by Enhanced Therapeutics, Inc. (ET), a new company formed by
Diagnon, JHU, certain JHU faculty members, and certain other investors.

During the second quarter of fiscal year 1995, the Company announced the
termination of the agreements between Diagnon and The Johns Hopkins University.
The termination was the result of the inability to obtain financing through a
private placement within the time-frame required by the agreements.  On
September 5, 1995, ET became a wholly owned subsidiary of Diagnon.

In fiscal year 1996, the Company's research and development activities in novel
forms of cancer treatment and drug delivery and purified IgG products were
assigned to the Company's Corporate Services business element and the first IgG
product, equine IgG was introduced.


CURRENT OPERATIONS

The Company is currently comprised of two subsidiaries, the above mentioned ET
and, BIOQUAL, Inc., which has two divisions, Medical Center Dr. Division and
Research Blvd. Division.

In fiscal year 1997, the BIOQUAL subsidiary is expected to generate more than
95 percent of the Company's revenues, with the remaining revenues arising from
the company's Corporate Support Services business element.  As revenues grow
from sales of IgG products and other research and development activities, the
Company may transfer these products and/or contracts to the currently inactive
ET subsidiary.





                                     - 1 -
<PAGE>   3
Financially and administratively, the Company's current business is divided
into three elements corresponding to the business emphases of BIOQUAL's two
divisions and the Corporate Support Services business element.

BIOQUAL MEDICAL CENTER DR. DIV. - immunological, reproductive and transgenic
studies and services with emphasis on small animal models.

BIOQUAL RESEARCH BLVD. DIV. - research and services in human disease using
nonhuman primate models.

CORPORATE SUPPORT SERVICES - purified IgG products, cancer treatment and drug
delivery.

   BIOQUAL, INC.

   MEDICAL CENTER DR. DIVISION

For the past twenty-one years, BIOQUAL, Inc. (through its Medical Center Dr.
Division since February 25, 1991) has operated cost-plus-fixed-fee ("CPFF")
contracts for the United States Government (the "Government") to provide
research and services in the areas of cancer, immunology, transgenics,
allophenic development, contraception and congenic animal breeding.  Currently,
the Medical Center Dr. Division operates six contracts which generate more than
85% of the division's revenue:

   1.   Maintenance of an Animal Holding Facility and provision of
        Attendant Research Services.  (ends 10/31/97)
   
   2.   Facility for Preparing and Housing Virus Infected Mice,
        Genetically Manipulated Mice and Chimeric Mice.  (ends 9/30/97)
   
   3.   Biological Testing Facility.  (Efficacy and Safety of
        Reproductive Compounds) (ends 5/31/01)
   
   4.   Provide Animal Housing/Maintenance/Bleeds/Immunizations as
        Specified Herein.  (ends 2/20/97)
   
   5.   Development of New Methods and Strategies for Diagnosis,
        Treatment and Prevention of Invasive Fungal Infection in Patients
        with Cancer and HIV Infection.  (ends 09/30/99)
   
   6.   Development of Transgenic Mouse Models for HIV Drug Testing.
        (ends 6/27/97)

Contract revenues are charged on the basis of direct labor and supplies
provided by the Medical Center Dr. Division.  Due to the relatively constant
required level of effort on the contracts, revenue is evenly spread over each
month of the year.  The Government traditionally pays promptly (barring any
unforeseen circumstances such as a government shut-down).  Medical Center Dr.
Division revenues totalled $4,851,581 for the most recent fiscal year.





                                     - 2 -

         RESEARCH BLVD. DIVISION

For over twenty-three years, BIOQUAL, Inc.; SEMA, Inc., prior to its merger
with BIOQUAL; (through its Research Blvd. Division since February 25, 1991),
have operated CPFF and Fixed Price contracts for the Government using nonhuman
primates to provide research and services in the disease areas of cancer, AIDS,
hepatitis, cystic fibrosis and influenza. Currently, Research Blvd. operates
five contracts:

         1.   Studies Using Primate Models for AIDS Vaccine Research.  (ends
              11/27/99)

         2.   Facility for Animal Models Utilized for Viral Hepatitis
              Experiments. (ends  12/27/99)

         3.   Facility for Nonhuman Primates Utilized in Infectious Disease
              Research.  (ends 12/30/99)

         4.   Mechanisms of Chemical Carcinogenesis in Old World Monkeys.
              (ends 12/18/00)

         5.   Care and Housing of SIV Infected Research Animals.  (ends
              01/18/00)

As part of the predecessor contract to the second contract listed above, the
Research Blvd. Division developed and has a patent on specially designed animal
housing units under the division's animal environmental enrichment program.

Contract revenues are charged on the basis of direct labor and supplies
provided by the Research Blvd. Division.  Due to the relatively constant
required level of effort on the contracts, revenue is evenly spread over each
month of the year.  The Government traditionally pays promptly (barring any
unforeseen circumstances such as a government shut-down). Contract revenues
totalled $3,942,063 for the most recent fiscal year.

BIOQUAL plans to bid on renewals for both divisions' contracts as they come up
for recompetition.

The Government is the major source of funding for all of BIOQUAL's services.
All of BIOQUAL's contracts are subject to renegotiation of profits or
termination at the election of the Government.  Termination of a contract or
failure to win a renewal competition adversely affects the Company's revenues
and operating capital until the vacated facility space is taken up by another
contract.

Small Business Innovative Research Program (SBIR)

Although the Company does not currently have any SBIR's, the Company continues
to compete for the Government's SBIR contract and ree grant mechanisms to
further the Company's proprietary research.  The Government offers to
commercial entities "Phase I" SBIR grants which are to fund feasibility studies
costing up to $100,000 and lasting six months. If the feasibility study shows
sufficient promise, then a "Phase II" program providing grants up to $700,000
may be awarded. "Phase III" of the program consists of establishing the project
on a commercial basis. The Company regularly submits SBIR proposals and has
been awarded and has completed four Phase I grants and one Phase II grant.
Proprietary positions and/or patents arising from these programs are the
property of the Company with free licensing available to the





                                     - 3 -
<PAGE>   5
Government. There can be no assurance, however, that additional SBIR grants
will be awarded, or that grants, if awarded, will result in proprietary
positions or patents for the Company.

         CORPORATE SUPPORT SERVICES (CSS)

CSS has one product in the marketplace, purified equine IgG which is sold under
the brand name Lyphomune(TM).  CSS is also responsible for the Company's
research and development activities, i.e.:

         - additional IgG products
         - cancer treatment and drug delivery


         EQUINE IgG PRODUCTION

In January, 1995, the Company entered into a Licensing and Manufacturing
Agreement with ZooQuest Technologies Ltd. for an exclusive worldwide license to
manufacture and sell Equine Immunoglobulin (Lyphomune(TM) IgG) purified by a
patented process assigned to ZooQuest.  Recently an agreement was reached for
the Company to acquire the assets of ZooQuest and the sale was completed in the
first quarter of fiscal year 1997.

The highly purified Equine IgG is used for treatment for Failure of Passive
Transfer (FPT) of immunity in newborn foals.

There are approximately 250,000 foals born in the United States annually. It is
estimated that 20-25% of these (about 55,000) will experience a failure of
passive transfer in some form which can be beneficially treated with Equine IgG
therapy.  The European Union produces in the vicinity of 40,000 foals annually
yielding an anticipated 9,000 with FPT.  Brazil presently has in the vicinity
of 6,000,000 horses yielding in the range of 150,000 new foals annually.  The
remainder of North and South America have an additional 17,000,000 horses with
upwards of 400,000 foals a year. Australia and New Zealand produce in the range
of 13,000 foals a year.  Treatment of a foal requires $60-$240 worth of the IgG
product.  The potential United States market is estimated at $6-8,000,000
annually and the remaining world wide market at an additional $18-20,000,000.
The Company will strive to capture as large a portion of the market as
possible, however, there can be no assurance of future sales.

The United States and Europe is the first market area for Lyphomune(TM).  A
distributor is presently serving the market in the U.S.  Other distributors are
being contacted to add to U.S. and international coverage.

         RESEARCH AND DEVELOPMENT

              CANCER TREATMENT AND DRUG DELIVERY

In the second quarter of fiscal year 1996, the Company hired a molecular
biologist to evaluate technologies available from the terminated Johns Hopkins
agreements and from other sources to develop a program in therapeutics for
certain human (e.g. cancer) and animal diseases.  At the end of fiscal year
1996, a novel approach to cancer treatment is under evaluation and if
preliminary studies show promise, the Company will seek support for further
development (e.g. SBIR contracts).





                                     - 4 -
<PAGE>   6
         Purified IgG Products

Currently the product, Lyphomune(TM), is being distributed as an oral dose. CSS
has initiated trials of an intravenous product which if successful would
provide a product with more direct entry to the bloodstream and thereby a more
efficient means for delivering the product.

Concurrently, the process for producing the oral product is being reviewed in
an effort to both increase the potency of the oral product and to lower unit
cost of production.

CSS is also working to produce purified IgG from serum from other species.
These IgG products will be clinically tested for efficacy.  If these IgG
products prove efficacious and capable of being delivered at an acceptable
market price, the Company will move to production of purified IgG for other
species.

BACKLOGS

Both the BIOQUAL Medical Center Dr. and Research Blvd. divisions operate under
Government contracts which typically run three to five years. Therefore, the
backlogs of the two divisions are significantly increased in a year in which a
long-term contract is awarded.  Most of the contracts included in the following
totals are incremental funded on an annual basis. Therefore much of the backlog
is not "firm" in that the funds will not be committed until a later date.

SUPERVISION AND REGULATION

         Animal Model Contracts

Over the last few decades, there has been an increasing awareness of the need
for adequate oversight and regulation of the utilization and husbandry of
animals.

BIOQUAL, Inc. utilizes animals and, by contract, is required to observe the
regulations and guidelines of the Department of Health and Human Services
Publication No. 85-23, revised 1985, Guide for the Care and Use of Laboratory
Animals. Furthermore, BIOQUAL, Inc. must meet the Public Health Service (PHS)
Policy on Humane Care and Use of Laboratory Animals. This policy mandates that
BIOQUAL, Inc. file annually an assurance as to compliance with the NIH Office
for Protection from Research Risks. BIOQUAL, Inc. also comes under the
jurisdiction of the U.S. Department of Agriculture (USDA), which regularly
inspects Research Blvd. Division and Medical Center Dr. Division facilities for
adherence to its rules and regulations regarding care and treatment of animals.
To ensure compliance with the several laws and regulations regarding animal
care, both Research Blvd. Division and Medical Center Dr. Division are
accredited as complying laboratories by the American Association for the
Accreditation of Laboratory Animal Care (AAALAC).

The supervision and regulation programs described herein are costly in terms of
ongoing operation and maintenance, but are essential because lack of compliance
can lead to cessation of operations and loss of contracts.

         Environmental Compliance

The Company incurs minimal costs in the disposal of the waste generated by its
operations.  These costs are reimbursable under government contracts.

         Veterinary Products

The USDA is responsible for regulation of veterinary products and the Company's
product testing, approval, production and packaging are governed by Part 9 of
the Code of Federal Regulations (CFR).

         Cancer Treatment Products

In the upcoming year, work on these products will not involve humans and thus
the Food and Drug Administration (FDA) will not be involved.  However, the work
leading up to FDA submission will be performed under Good Laboratory Practices
(GLPs) in order to be acceptable for future presentation.  Any work involving
animals will also fall under regulation by the entities described in the prior
"Animal Model Contracts" discussion.

COMPETITION

         Animal Model Contracts

The Company is classified as a "small business" in Government contracting
procedures.  So long as the Company continues to qualify as a "small business,"
this classification effectively limits competition for several of the Company's
current research contracts to other "small businesses" in the Washington, D.C.
area.  Other barriers to competition include the general requirement of
location in the D.C. area (to serve the NIH scientists) and the high capital
costs to establish animal holding facilities.





                                     - 6 -
<PAGE>   8
The Company's main "small business" competitors are Taconic Farms, BIOCON, ROW
Sciences, and Microbiological Associates.

The Company also competes on open contracts for animal research work and its
competitors at this level are Hazelton, ABL, Bionetics and universities.

Due to the specialized nature of the work and the facilities, relatively few
companies compete for contracts in small animal and nonhuman primate
applications.  The Government selects winners among the competitors through
evaluation of the merit of the written technical proposals with price being an
important but not an overriding factor.

         Veterinary Products

Equine IgG, the Company's product which was introduced into the market this
past fiscal year, is a purified immunoglobulin sold as a lyophilized
(freeze-dried) product.  Competing products currently on the market involve the
use of unpurified equine serum/plasma maintained in a liquid or frozen state
(thawed for use).  Principal suppliers of these competing alternative products

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR
         PLAN OF OPERATION

Liquidity and Capital Resources

The Company currently has a $1,000,000 secured revolving line of credit with
First National Bank of Maryland.  This line of credit is annually renewable and
the Company believes, although there is no assurance, that the line of credit
will be renewed in October, 1996.  As of May 31, 1996, there were no borrowings
under this line of credit.  In the opinion of the Company, total current
assets, the line of credit resources and the capital provided by future
operations will provide adequate liquidity and capital resources to maintain
operations.

The Company leases equipment under various capital leases which expire in
fiscal years 1999, 2000 and 2001.  At May 31, 1996, the present value of the
minimum lease payments was $402,263.

The Company's revenues result primarily from Government CPFF and Fixed Price
contracts.  Continued success in winning these contracts is essential to
maintaining liquidity and capital resources.  Since the 1995 FORM 10-KSB
report, the following material contracts have been awarded to the Company:

<TABLE>
<S>                                <C>
1. Title:                          Mechanisms of Chemical Carcinogenesis in Old World
                                   Monkeys.
   Institute:                      National Cancer Institute
   Dates Funded:                   12/19/95 -12/18/00
   Contract Funding:               $3,266,150
                                  
                                  
2. Title:                          Biological Testing Facility.
   Institute:                      National Institute of Child Health and Human
                                   Development
   Dates Funded:                   7/1/96 - 6/30/01
   Contract Funding:               $15,015,891
</TABLE>                          

During this fiscal year, there were two external factors which significantly
affected the financial results of the Company:  1) the shut-down of the Federal
Government and 2) a severe snowstorm in the Washington, D.C. metropolitan area
in January 1996 ("Blizzard of '96").  The government shut-down created
operational delays within existing contracts held by the Company's subsidiary,
BIOQUAL, Inc., as well as delayed potential contract negotiations.  The
shut-down also had a negative impact on the Company's ability to make timely
collections of accounts receivable on its federal contracts.  The result of the
poor collections rate was increased borrowings on the Company's line of credit
and increased interest expense during the third quarter of this fiscal year.

The "Blizzard of '96" caused a decrease in the Company's direct labor base, and
consequently sales, during the third quarter as many of the Company's employees
were unable to report to work during the storm.  The Company's





                                     - 9 -
<PAGE>   11
sales are generated mainly from cost reimbursable contracts with direct labor
being the primary producer of sales.

In addition to the two external factors above, the expiration of two contracts
on May 31, 1995 and June 30, 1995 (representing approximately 13.4% of the
prior year sales) has had a significant impact on the Company this fiscal year.
The Company is continuing its efforts to replace the expired contracts.

Changes in Financial Position - 1996 versus 1995

Assets

In the twelve months of operation in this fiscal year, Total Assets increased
$292,415.  This amount is primarily attributable to an increase in Fixed
Assets, net of Accumulated Depreciation and Amortization of $304,360,
reflecting an increase in fixed asset purchases of $574,421 (mainly nonhuman
primate enclosures and an autoclave) offset by depreciation and amortization of
$270,061 during this fiscal year. Inventories increased $52,755 as the Company
continues to produce Equine IgG.  The balance of the increase is due to other
miscellaneous factors.

The increases above were partially offset by: a decrease to Accounts Receivable
of $45,196 consisting mainly of 1) a $105,801 decrease to Unbilled Accounts
Receivable resulting from a $232,973 decrease in reimbursable indirect rate
variances as a result of collections of previously unbilled variances from
prior fiscal years and a $127,171 increase in the accrual of unbilled direct
costs that were billed in the subsequent fiscal year, and 2) an increase of
$57,240 to Trade Accounts Receivable.  Other Noncurrent Assets decreased
$28,677 primarily due to the net result of the completion of a nonhuman primate
housing unit order ($52,553) from the previous fiscal year and a $24,226
increase in the cash surrender value of a $1,000,000 split dollar life
insurance policy held by John C. Landon, the President, and the Company.

Liabilities

In the twelve months of operation in this fiscal year, Total Liabilities
increased $200,217.  This amount is primarily due to an increase in Long-Term
Debt of $176,376 related to capital leases of $289,614 for nonhuman primate
enclosures at the Research Boulevard Facility, offset by $113,238 of payments
on capital leases, and an increase in Accounts Payable of $18,926.  The balance
of the increase is due to other miscellaneous factors.

Changes in Financial Position - 1995 versus 1994

Assets

In the twelve months of operation in fiscal year 1995, Total Assets decreased
$1,117.  This amount was primarily attributable to a decrease to Accounts
Receivable of $65,908 consisting of 1) an decrease of $380,609 to Trade
Accounts Receivable reflecting faster than normal collections compared to the
prior fiscal year end, 2) a $361,677 increase to Unbilled Accounts Receivable
resulting from a $356,284 increase in reimbursable indirect rate variances and
a $5,393 increase in the accrual of unbilled direct costs that were billed in
the subsequent fiscal year, and 3) Other Receivables decreased by $46,976
primarily due to the write off of the $119,000 receivable from Enhanced
Therapeutics, Inc., of which $51,078 was receivable at May 31, 1994.





                                     - 10 -
<PAGE>   12
Deferred Income Taxes decreased by $181,900 primarily as a result of utilizing
a portion of the federal income tax loss carryforward during last fiscal year.
Loans to Officers decreased by $10,000 reflecting payments made by the Chief
Operating Officer to fully repay his loan from the Company.  The balance of the
decrease was due to other miscellaneous factors.

The decreases above were partially offset by an increase to Cash and Cash
Equivalents of $153,581 reflecting faster than normal collections compared to
the prior year end.  Prepaid Expenses increased $12,257 primarily due to a
$10,463 increase in employee salary advances.  Other Noncurrent Assets
increased $90,736 primarily due to a $52,553 deposit on the fabrication of
thirteen nonhuman primate housing units and a $37,833 increase in the cash
surrender value of a $1,000,000 split dollar life insurance policy held by John
C. Landon, the President, and the Company.

Liabilities

In the twelve months of operation in  fiscal year 1995, Total Liabilities
decreased $122,547.  This amount was primarily due to:  1) a decrease to
Borrowings Under Line-of-Credit of $154,967, 2) a decrease in Deferred Income
of $86,579 related to the specially designed animal housing units fabricated
under the Federal Government contract "Facility for Animal Models Utilized for
Viral Hepatitis Research", and 3) a decrease in Other Accrued Liabilities of
$26,640. The balance of the decrease is due to other miscellaneous factors.

The decreases above were partially offset by an increase in Long-Term Debt of
$126,393 related to capital leases of $189,718 for nonhuman primate enclosures
at the Research Boulevard Facility and the refinancing of other existing
capital leases, offset by $75,715 of payments on capital leases, and an
increase in Accounts Payable of $29,866.

Results of Operations  - 1996 versus 1995

Revenues

Contract revenues decreased by 6.8% compared to the prior year primarily due to
decreased contract activity (two contracts ended at the end of fiscal year 1995
and the first quarter of this fiscal year respectively representing
approximately 13.4% of the prior fiscal years sales).  Also affecting this
fiscal year's sales is approximately $34,700 of applied indirect costs on four
contracts which caused the total incurred costs of each contract to exceed its
funding.  These indirect costs are currently not available for reimbursement
and therefore revenue cannot be recognized. According to Federal Acquisition
Regulations, the Company may be able to recover all or part of these costs
after a government indirect cost audit for this fiscal year has been completed.

Operating Expenses

Contract expenses decreased 3.9% compared to the prior year primarily due to a
decrease in contract activity offset by costs incurred associated with the
production of Equine IgG which the Company began to market and sell this fiscal
year and research and development (R&D) expenses incurred related to certain
cancer treatment and drug delivery approaches.  General and Administrative
Expenses (G&A) decreased 8.2% compared to the prior fiscal year.  The decrease
is primarily due to the net result of a prior year $119,000 write off related
to the termination of the agreements between





                                     - 11 -
<PAGE>   13
Diagnon and The Johns Hopkins University and increases in current year expenses
resulting from annual salary increases and the addition of a full-time legal
counsel.  Also contributing to the decrease is a reduction of the use of
outside legal counsel as compared to the prior year.  The combination of these
decreases resulted in an overall decrease in operating expenses of 4.8%.

Operating Income

Operating income decreased 56.8% compared to the prior year due to decreased
contract activity, costs incurred associated with the production of Equine IgG,
R&D expenses relating to certain cancer treatment and drug delivery approaches,
and the "Blizzard of '96" as previously discussed.

Interest Expense

For this fiscal year, Diagnon had interest expense of $49,602 compared to
$49,086 in the prior year.

Provision For Income Tax

In accordance with SFAS No. 109, "Accounting for Income Taxes", the Company
reported deferred federal income tax benefit of $2,300 for the year ended May
31, 1996.  The Company provided for state income tax which is estimated at
$27,600.  State income tax expense is reimbursable under government contracting
regulations.

Results of Operations  - 1995 versus 1994

Revenues

Contract revenues increased by 5.1% over 1994 primarily due to increased
contract activity.  Also affecting last fiscal year's sales was approximately
$83,800 of applied indirect costs on six contracts which caused the total
incurred costs of each contract to exceed its funding. These indirect costs
were not in fiscal year 1995 and are currently not available for reimbursement
and therefore revenue could not be recognized on these costs in fiscal year
1995.  According to Federal Acquisition Regulations, the Company may be able to
recover all or part of these costs after a government indirect cost audit for
fiscal year 1995 has been completed.

Operating Expenses

Contract expenses increased 4.0% and General and Administrative expenses
increased 18.5% over 1994.  The increases were primarily due to increased
contract activity in on-going contracts and the $119,000 write off related to
the termination of the agreements between Diagnon and The Johns Hopkins
University as previously discussed herein.  The combination of these increases
resulted in an overall increase in operating expenses of 6.6%.

Operating Income

Operating income decreased 22.0% compared to 1994 due to the $119,000 write off
mentioned above and the effect of the indirect costs mentioned above, offset by
relatively higher profit margins on fixed price contracts as compared to 1994.





                                     - 12 -
<PAGE>   14
Interest Expense

For fiscal year 1995, Diagnon had interest expense of $49,086 compared to
$34,568 in the prior year.  This increase is primarily attributable to the
increased Borrowings Under Line-of-Credit and capitalized leases at a higher
interest rate.

Provision For Income Tax

In accordance with SFAS No. 109, "Accounting for Income Taxes", the Company
reported deferred federal income tax expense of $181,900 for the year ended May
31, 1995.  The Company provided for state income tax which is estimated at
$23,900.  State income tax expense is reimbursable under government contracting
regulations.

Inflation and Price Changes for Fiscal Year

For fiscal years 1994, 1995, and 1996 neither inflation nor price changes had
any material effect on net sales, revenues, or income from operations.

COMPENSATION PURSUANT TO PLANS

Stock Option Plan - The Company adopted a Stock Option Plan (the "Plan") in
November 1988 which permits the granting of options to all employees to
purchase up to an aggregate of 500,000 shares of Common Stock.  The Plan is
designed to qualify as an "incentive stock option plan" under Section 422A of
the Internal Revenue Code, but also permits the Company to grant non- qualified
options to persons, such as consultants and outside directors. Under the Plan,
options to purchase shares of Common Stock are granted at not less than 100% of
the fair market value of the underlying shares on the date granted.  The Plan
is administered by a committee of the Board of Directors, which has the
authority to select optionees, evaluate suggestions presented by the Company in
order to determine the number of options to be granted to the selected
optionees, designate the number of shares to be covered by each option and,
subject to certain restrictions, specify other terms of the options.  During
fiscal year 1996, the committee was comprised of Messrs. Gauvin and Francisco.

ITEM 12.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

On June 1, 1988 the Company and Dr. Landon agreed to consolidate the previous
loan facilities available to Dr. Landon into a single loan of $100,000.  The
loan had a five year term with repayment of principal deferred for three years.
The loan bears interest at the six month certificate of deposit rate paid by
Signet Bank, Maryland and the rate is adjusted quarterly.  On September 29,
1989 the Company agreed to increase the loan to $125,000.  On September 21,
1990, the Company agreed to increase the loan to $150,000.  Pursuant to Dr.
Landon's current employment agreement, the loan is to be repaid in five
installments of $30,000 plus interest within six weeks after the end of each of
the next five fiscal years beginning with fiscal year 1992.

The largest amount owed by Dr. Landon during the fiscal year ended May 31, 1996
in respect to his loan facilities was $90,000, excluding interest accrued
amounting to $8,955.  There was no addition to the loan during this fiscal
year.  On July 1, 1994, Dr. Landon made a payment of $2,745 on accrued
interest.  On June 6, 1994, the Company agreed to defer Dr. Landon's third
$30,000 repayment and make the payment due as two $15,000 installments paid
with the fourth and fifth $30,000 repayments respectively.  On October 11,
1995, the Company's shareholders affirmatively voted to approve the purchase

of Company stock from Dr. Landon at market value to fund the repayment by Dr.
Landon of the remainder of the Company loan.  As of July 29, 1996, neither the
stock purchase or the loan repayment transaction has occurred.

INDEPENDENT AUDITORS' REPORT


Diagnon Corporation:

We have audited the accompanying consolidated balance sheets of Diagnon
Corporation and Subsidiaries as of May 31, 1996 and 1995, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the years in the three year period ended May 31, 1996.  These financial
statements are the responsibility of the Corporation's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Diagnon Corporation and
Subsidiaries at May 31, 1996 and 1995, and the results of their operations and
their cash flows for each of the years in the three year period ended May 31,
1996 in conformity with generally accepted accounting principles.

DIAGNON CORPORATION AND SUBSIDIARIES

NOTES TO FINANCIAL STATEMENTS

- - ---------------------------------------------------------------------------


1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation

The accompanying consolidated financial statements include the accounts of
Diagnon Corporation (the "Company") its wholly-owned subsidiaries, BIOQUAL,
Inc. and Enhanced Therapeutics, Inc.  All significant intercompany transactions
and balances are eliminated in consolidation.

Segment Information

The Company's principal business consists of the government contract research
operations.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period.  Actual results could differ from those estimates.

Fixed Assets and Depreciation

Fixed assets are stated at cost.  Depreciation is provided for financial
reporting purposes using the straight-line method over the estimated useful
lives of the assets (generally three to ten years).  Tax depreciation is
provided on the straight-line method.  Leasehold improvements are amortized
over the lease period or the estimated useful life of the improvements,
whichever is shorter.

Inventories

Inventories are stated at the lower of cost or market.

Research and Development

All costs incurred in connection with any research and development activities
are expensed as incurred.

Revenue Recognition

Contract research revenue is generally earned based on cost-plus-fixed-fee
("CPFF") arrangements and is recognized as costs are incurred.

Income Per Share

Income per share is computed based on the weighted average number of common
shares outstanding during each period.  In 1996, 1995 and 1994, common stock
options were not included in the calculation of earnings per share because they
had an immaterial effect (less than 3%).

exception of the CEO's option which expires January 19, 1999, options expire
ten years from date of grant under the plan, or upon the optionee's separation
from the Company and were granted at the average of the closing bid and ask
price of the Company's Common Stock at the date of grant.  The Company has

of options granted outside its 1988 stock option plan. Option transactions were

The equipment is amortized on a straight-line basis over the estimated useful
life of the equipment.  Amortization expense amounted to $33,516, $66,700 and
$51,510 in 1996, 1995 and 1994, respectively, and is included with depreciation
expense in the financial statements.

The fair value of long-term debt is estimated to approximate its carrying value
at May 31, 1996 based on borrowing rates currently available with similar terms
and maturity.

5.  INCOME TAXES

Income taxes are accounted for using Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes" (SFAS No.  109), which
requires an asset and liability approach to financial accounting and reporting
for income taxes.  Under SFAS No. 109, deferred tax assets and liabilities are
provided for differences between the financial statement and tax bases of
assets and liabilities that will result in future taxable or deductible
amounts.  The deferred tax assets and liabilities are measured using the
enacted tax laws and rates applicable to the periods in which the differences
are expected to affect taxable income.  Income tax expense is computed as the
tax payable or refundable for the period plus or minus the change during the
period in deferred tax assets and liabilities.

</TABLE>

As of May 31, 1996, the Company has cumulative tax operating loss carryforwards
of approximately $4,600,000 available to reduce future federal  taxable income.
The operating loss carryforwards expire in fiscal years 1998 to 2003.  During
the three year period ended May 31, 1996, the Company utilized $747,000 of tax
loss carryforwards.  Management believes that it is more likely than not that
the Company will generate future taxable income sufficient to realize a portion
of the remaining tax loss carryforward and that the valuation allowance is
appropriate given the current estimates of future taxable income.

6.  COMMITMENTS AND CONTINGENCIES

Leases

The Company is a lessee under various noncancelable operating leases, covering
the facilities in which its operations are conducted and certain equipment and
vehicles.  During 1996, 1995 and 1994, the Company subleased a part of its
premises.  As of May 31, 1996, there are no material sublease agreements.  The
rental income earned has been offset against the Company's rental expense in
the period.  The aggregate minimum annual rental commitments under these
various leases are as follows:

   Notwithstanding the Clause ALLOWABLE COST AND PAYMENT (and FIXED FEE, if
applicable) referenced in SECTION I of this contract, unless authorized in
writing by the Contracting Officer, the costs of the following items or
activities shall be unallowable as direct costs:

    (1)   Acquisition, by purchase or lease, of any interest in real property;

    (2)   Special rearrangement or alteration of facilities;

    (3)   Purchase or lease of ANY item of general purpose office furniture or

                                      B-2
<PAGE>   8
   NO1-HD-6-3259                                                     Section B

performance of this contract shall not exceed $.00 without the prior written
approval of the Contracting Officer.

         b.   This contract is subject to the provisions of Section 24 of
Public Law 99-234 which amends the Office of Federal Procurement Policy Act to
provide that contractor costs for travel, including lodging, other
subsistence, and incidental expenses, shall be allowable only to the extent
that they do not exceed the amount allowed Federal employees.

   The contractor, therefore, shall invoice and be reimbursed for all travel
costs in accordance with Federal Acquisition Regulations (FAR) 31.205-46.

    (2)  Foreign Travel

         Requests for foreign travel must be submitted at least six weeks in

         c. Contract purposes to be served by the travel;

         d. How travel of contractor personnel will benefit and contribute to
            accomplishing the contract project, or will otherwise justify the

         e. How such advantages justify the costs for travel and absence from
            the project of more than one person if such are suggested; and

         f. What additional functions may be performed by the travelers to
            accomplish other purposes of the contract and thus further benefit
            the project.

B.6   PRE-CONTRACT COSTS  (NIH 3000) (JUL 1986)

   Within the dollar limitation set forth under this SECTION B, below, the
Contractor shall be entitled to reimbursement for costs incurred during the
period July 1, 1996 through August 31, 1996 in an amount not to exceed
$465,595.00, which if incurred after this contract had been entered into,
would have been reimbursable under the provisions of this contract.

B.7   FEE TIED TO LEVEL OF EFFORT   (NIH 3005)  (JUL 1986)

   The fixed fee shall be paid in direct ratio to the level of effort
expended; that is, the percent of fee paid shall be equal to the percent of
total effort expended.  Payment shall be subject to the withholding provisions
of the Clauses ALLOWABLE COST AND PAYMENT, and FIXED FEE referenced in SECTION

fixed fee shall not be made in less than monthly increments.

B.8   GOVERNMENT DISCOUNT AIR TRAVEL RATES  (NIH 3161) (MAY 1989)

   (a)  To the maximum extent practicable consistent with travel requirements,
the contractor agrees to use the reduced air transportation rates and services
provided through available government discount air fares.  These fares are
available only for bona-fide employees' travel that is otherwise reimbursable
as a direct cost pursuant to this contract.  The objective is to achieve the
lowest overall cost to the contractor and, thus, to the Government.  The
contractor shall submit written requests to the contracting officer for
authorization to use these rates.  The request shall provide the full name of
the traveler(s), the number of the contract for which the travel is being
performed, the contract objective that is to be fulfilled, and the dates
during which the travel is to occur.  Contracting officer approval, if given,
will be on official agency letterhead so that the letter can be presented to
the airlines as confirmation of the authorization.

   (b)  Nothing in this clause shall authorize transportation or services
which are not otherwise reimbursable under this contract. Nothing in this
clause requires air carriers to make available to the contractor any
government discount air fares.

production bottlenecks of a sporadic nature;

     (2)  By indirect-labor employees such as those performing duties in
connection with administration, protection, transportation, maintenance,
standby plant protection, operation of utilities, or accounting;

     (3)  To perform tests, industrial processes, laboratory procedures,
loading or unloading of transportation conveyances, and operations in flight or
afloat that are continuous in nature and cannot reasonably be interrupted or
completed otherwise; or

Preparation, Handling and Administration of Test Materials

         A. Precautions

            Contractor will be expected to take all necessary and reasonable
            precautions to protect employees handling test materials and will
            supply suitable protective clothing and equipment.  Employees will
            follow procedures consistent with acceptable laboratory practice
            designed to guard against personal injury.

         B. Physical Properties

            1.   Whenever possible, physical data such as solubility, m.p.,
                 b.p., stability and potential hazards in use will be supplied
                 with the test material.

            2.   Compounds known or suspected to be unstable will be handled
                 strictly according to instructions supplied with the Compound
                 Submission Form.

         C. Storage

            Compounds received for testing shall be stored under refrigeration
            (approximately 5 degrees C) unless otherwise specified.  
            Formulations of test materials remaining after medication will
            usually be discarded but under unusual circumstances CDB may
            request that contractors store these preparations.  Storage of test
            materials under nitrogen, under desiccation, and/or at low
            temperatures (approximately -20 degrees C) may be required for some
            test materials.

         D. Preparation

            1.   Instructions for preparing test materials will usually be
                 provided on the Compound Submission Form.

            2.   Where compounds are not soluble in the recommended vehicle,
                 contractor will contact the Project Officer to discuss
                 alternative vehicles.  When suspensions are to be employed,
                 every effort will be made to reduce particle size to a minimum
                 by non-destructive methods.

            3.   The following vehicles will usually be used in the formulation
                 of test compounds:  distilled water, sterile saline, ethyl
                 alcohol, various buffers and various pH's, propylene glycol,
                 sesame oil, olive oil, corn oil, and aqueous suspending
                 vehicle (0.9% sodium chloride, 0.4% polysorbate 80, 0.5%
                 carboxymethylcellulose and 0.9% benzyl alcohol).

            4.   Dilution of the initial concentration of test material in
                 vehicle will be made so that the volume remains constant for
                 each dose level employed.
<PAGE>   36
EXHIBIT III - Page 2

            5.   Following the preparation of appropriate concentrations of the
                 test material for each dose level to be employed, all
                 solutions (suspensions) will be stored under refrigeration in
                 air-tight vessels. Test solutions will be brought to room
                 temperature prior to administration and returned to the
                 refrigerator immediately following medication.

            6.   Should test materials come out of solution following
                 refrigeration and remain so after attaining room 
                 temperature, warming the preparation to redissolve the test
                 material will be permitted to the extent indicated on the
                 Compound Submission Form.

         E. Administration

            1.   Test materials will be administered as indicated on the
                 Compound Submission Form.  Ball-tipped needles in the largest
                 gauge (smallest diameter) consistent with the passage of
                 vehicle employed will be used for gavaging animals.

            2.   In addition to oral administration, medication by
                 intramuscular, intravenous, intraperitoneal, subcutaneous and
                 subdermal injections will be employed where specified.

            3.   Dilution of stock solutions (suspensions) will be made so that
                 the volume to be administered for each dose level remains
                 constant.

            4.   Separate syringes and needles will be used for each dose
                 level.

            5.   In general, the volume of vehicle containing test material
                 will be between 0.1 and 1.0 ml in rats, between 0.1 and 5.0
                 ml in rabbits and up to 10 ml in monkeys.  The smallest
                 feasible volume in the ranges shown above will be utilized.

            6.   Control animals will ordinarily receive an equivalent volume
                 of the vehicle used for the test material.

            7.   In those tests requiring a comparison of the biological
                 activity of experimental substances with that of known
                 standards (determination of potency estimates, relative
                 potency, etc.), the standard employed will be administered in
                 the same vehicle as that of the test material with which a
                 comparison is being made.

         F. Selection of Dose Levels

            1.   In general, dose levels will be selected which will provide
                 the data required most expeditiously.

            2.   Dose levels for each test substance will ordinarily be
                 specified on the Compound Submission Form.

INVOICE/FINANCING REQUEST INSTRUCTION FOR NIH COST-REIMBURSEMENT TYPE CONTRACTS

GENERAL:  The contractor shall submit claims for reimbursement in the manner
and format described herein and as illustrated in the sample invoice/financing
requests.

FORMAT:   Standard Form 1034, "Public Voucher for Purchases and Services Other
Than Personal"; and Standard Form 1035, "Public Voucher for Purchase and        
Services Other Than Personal -- Continuation Sheet", or reproduced copies of
such forms marked ORIGINAL should be used to submit claims for reimbursement. 
In lieu of SF-1034 and SF-1035, claims may be submitted on the payee's
letter-head or self-designed form provided that it contains the information
shown on the sample invoice/fancing request.

NUMBER OF COPIES:   As indicated in the Invoice Submission clause in the
contract.

FREQUENCY:   Invoices/financing requests submitted in accordance with the
payment clause shall be submitted monthly unless otherwise authorized by the
contracting officers.

COST INCURRENCE PERIOD:  Costs incurred must be within the contract performance
period or covered by precontract cost provisions.

BILLING OF COSTS INCURRED:   If billed costs include:  (1) Costs of a prior
billing period, but not previously billed, or (2) costs incurred during the
contract period and claimed after the contract period has expired, the amount
and month(s) in which such costs were incurred shall be cited.

CONTRACTOR'S FISCAL YEAR:  Invoice/financing requests shall be prepared in such
a manner that costs claimed can be identified with the contractor's fiscal
year.                      

CURRENCY:   All NIH contracts are expressed in United States dollars.  Where
expenditures are made in a currency other than United States dollars, billings
on the contract shall be expressed, and reimbursement by the United States
Government shall be made, in that other currency at amounts coincident which
actual costs incurred. Currency fluctuations may not be a basis of gain or loss
to the contractor.  Notwithstanding the above, the total of all invoices paid
under this contract may not exceed the United States dollars authorized.

COSTS REQUIRING PRIOR APPROVAL:  Costs requiring the contracting officer's
approval which are not set forth in an advance understanding in the contract
shall be so identified and reference the Contracting Officer's Authorization

                 completion invoice should be submitted when all costs (except
                 for finalization of indirect cost rates) have been assigned
                 to the contract and all performance provisions have been
                 completed.

                 the amounts owed have been settled between the government and
